Dear Hooligan

Swiss police sent letters to around 300 known football hooligans warning them that no violence would be tolerated during EURO 2008. The letter said: "We know that you are someone who does not always hold fast to to the rules in sports events. Therefore, to our knowledge, you have been banned from the stadium or served with other measures. We wish you too could enjoy this major sports event in a sportsmanlike and festive fashion."

As it began politely, the letter also concluded amicably: "We hope that we would only encounter each other in a pleasant manner. In case you have any questions, please get in touch with us."
